I think the problem with healer is not that the dev didnt have the ability to make it more complex or interesting, its more of trust issue, the dev didnt believe that most player will play healer if healing is harder than how it is today, like, how many healer actually remember to use lucid dream in order to sustain their MP anyway? Sage has many damage stuff to do and shielding will also reward you with extra damage kit, they should make all healer have fun stuff like this....
